JAMES SIMPSON, OF LIVERPOOL, COUNTY OF LANCASTER, ENGLAND.

LID FOR METALLIC DRUMS.

SPECIFICATION forming part of Letters Patent No. 374,276, dated December6, 1887.

Application filed October 5, 1887. Serial No. 251,562. (No model.)Patented in England January 10, 1887, No. 334.

To aZZ whom it may concern:

Be it known that I, JAMES SIMPsoN, of Liverpool, in the county ofLancaster, England, have invented a new and useful Improvement in Lidsor Closers for Metallic Drums, (for which I have received Letters Patentin England, No. 33l, dated January 10, 1887;) and I do hereby declarethe following to be a full, clear, and exact description thereof.

This invention relates to improved lids or closers for metallic drums,which are secured to the vessels by means of lateral lugs or projectionson the lid, which fit under the rim of the drum at the edges of theaperture thereof, such as are described in the specification to myUnited States Patent No. 188,197, March 6, 1877.

It has been found in practice that when lids I or closers such as aredescribed in the specification above mentioned are used great care mustbe taken to make that part of the lid or closer next the lateralprojections the exact size of the hole in the head of the drum, for ifthat part of the lid is larger than the hole there is great difficultyin fixing the said lid or closer, and if smaller than the hole'unclosedapertures are left at each side of the lateral projections.

Now, the object of my invention is to so improve the said lidsor,closers that they may be small enough at the parts named to beeasilyfixed, and yet apertures will not be left at the points of junction ofthe lateral projections and lid or closer with the head of the drum.

My invention consists in the combination, with a lid for metallic drumshaving lateral projections which fit under the head of the drum and lockthe lid in place over the filling-aperture, of a soft or elasticpacking-- such as string, cord, guttapercha, soft-metal Wire, and likesubstances-which is passed over the projections at their surfacesofjuncture with the body of the lid, so that when the lid is set inplace and secured by means of the projections there shall be no vacantspaces at the edges of these projections.

Figure l is a plan, Fig. 2 a view of the under side, Fig. 3 alongitudinal section on the line as a: of Fig. 1, and Fig. 4 atransverse section on the line y y of Fig. 2, of a lid or closer of themost approved construction under my invention. 1, body of lid; 2,lateral projections; 3, grooves in the under face of the lid or closer;4, apertures at the extremity of the lid or closer; 5, string, cord, orother suitable packing. The string or cord passes over the upper edgesof the lateral projections along the grooves in the under side andthrough the apertures at.

Fig. 5 is a plan, and Fig. 6 an elevation, of a modification of myimproved lid or closer; and Fig. 7 is a detail view of a-partillustrating a modified form of my invention. 1, body of lid; 2, lateralprojections; 5, string or cord passed over the upper edges of thelateral projections and beneath the body of the lid, where the ends ofthe string are tied or secured at 6 to keep it in its place.

Instead of passing the string or its equivalent directly from onelateral projection to another, it may be made to cross, as shown by thedotted lines 7, the ends being brought to the crossing, where they aresecured by cement-such as pitchapplicd when melted.

Instead of one piece of string or its equivalent, two pieces may be usedand the ends secured to the lid or closer by means of cement or othersuitable adhesive substance. When metal is used, the ends are solderedor twisted together or secured by clips, splicing, or in any suitableway. Rings or ferrules of soft metal, as shown in Fig. 7, may be made tofit over the lateral projections and be retained in position by frictionor cement, the main feature being the provision of a soft or resilientpacking at the points of juncture of the lid or closer with the head ofthe drum or cask.

I claim- 1. The combination, with a lid or closer for metallic drumshaving projections 2, which fit under the head of the drum and confineit in place, of a soft packing which is passed over the projections attheir juncture with the body of the lid, substantially as and for thepurposes described.

2. In a lid or closer for metallic drums, the combination of the body 1,lateral projections 2, grooves 3, and apertures 4, with packing 5, forthe purpose set forth.

In testimony whereof I have hereunto set my hand this 23d day ofSeptember, 1887.

JAMES SIMPSON.
